Large Venues: Not Your Ordinary Project
Planning Considerations • Coverage area (sq meters/miles)• Number of devices on network• Number of networks • Overall costs (CAPEX and OPEX)
• Who’s paying the bill? • Revenue opportunities?
• Bandwidth • Temporary bandwidth • Security
Every Site Has Unique Challenges
Challenges
Size Shape Capacity Architecture Location
• High-density public venues
• New connections joining the Wi-Fi network
• How the world engages with Wi-Fi networks, demand for advanced Wi-Fi technologies
• “High-resolution video streaming, Wi-Fi calling, smart home monitoring, hotspot access, automation of citywide services, residential AR/VR applications and seamless roaming” [Source: Wi-Fi Alliance]
• IP-enabled intelligent buildings confirm how Wi-Fi will continue to be the connectivity of the future.

Topology
Topology of the Network
• Goal: To maintain a star-wired network topology– Distance makes it difficult to maintain – Intermediate points must be utilized
• All wireless access points must be wired! • Wireless access point zones
– Normal coverage areas – Heavily used spots – Revenue opportunities

Access Points Mounting
Mounting the access points with integrated antennas in the preferred horizontal orientation will permit full performance of the AP. This is always recommended by the manufacturer.
Serviceability Method: Quick and Easy
• Rapid access to the AP and the cabling components can help reduce time and cost.
• Choose a method of installation that offers a quick migration path to future AP upgrades
Interchangeable doors for quick, easy upgrades

NEMA 4: Outdoor Protection
When extending the Wi-Fi infrastructure from indoors to outdoors, physically secure and protect the AP and components from weather, impact and vandalism.
